Filter by:The primary objective of this study is to perform mass balance following a single oral dose of [14C]CCX168 in healthy adult male participants.
The primary objective of this study will be to evaluate the drug-drug interaction potential of CCX168 with concomitant medications, as either a perpetrator or a victim, following oral administration of CCX168 to healthy participants.
The primary objective of this clinical trial is to evaluate the effect of a high-fat, high-calorie meal on the pharmacokinetic (PK) profile of CCX168, following oral administration of a single dose of 30 mg CCX168 to healthy volunteers.
The objectives of the study will be to investigate the safety and pharmacokinetics of a single oral administration and a twice-daily multiple oral administration of CCX168 in Japanese healthy adult males; and to compare the pharmacokinetics of a single oral administration and a twice-daily multiple oral administration of CCX168 between Japanese and Caucasian healthy adult males.
The primary objective of this study will be to evaluate the safety and tolerability of single and multiple oral doses of CCX168, over a range of dose levels, in healthy male and female participants.
A screening of patient histories at the clinics of Dermatology of the universities of Zurich, Basel and Bern is performed in order to identify patients with a history of Livedoid vasculopathy. Patients with a history of livedoid vasculopathy are asked to participate in the study. After reading the patient information and if the informed consent is signed patients are included in the study. Patients are questioned about their smoking history and blood is drawn in order to perform a screening for thrombophilia.
An Open-label, Single-ascending dose, Phase I Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of STSA-1002 Subcutaneous Injection in Healthy Subjects
This non-interventional descriptive study was undertaken to better understand the most common imaging features associated with inflammation arising in the post-marketing setting when brolucizumab was prescribed in routine clinical practice.
Giant cell arteritis (GCA) is the most common vasculitis in the elderly. Accurate diagnosis is of utmost importance in order to then initiate the necessary immunosuppressive therapy. For large-vessel GCA (LV-GCA) involving the aorta and its branches, FDG-PET/CT is the standard in imaging for diagnosis and is recommended by the guidelines. However, this only indirectly visualizes inflammation through vessel wall uptake of glucose. A new PET tracer, 68Ga-pentixafor, is used to visualize the chemokine receptor CXCR4. This receptor is expressed by cells of the immune system. In the context of inflammatory processes, upregulation of CXCL12, the ligand of CXCR4, occurs in affected tissues. The chemotactic effect of this ligand leads to the immigration of CXCR4-positive inflammatory cells into the inflamed area, which can be visualized by PET using the CXCR4-specific tracer 68Ga-Pentixafor. The value of CXCR4-PET should therefore be tested in the context of LV-GCA. This study tests the benefit of CXCR4 in therapy-naïve patients with suspected LV-GCA. For this purpose, patients will receive a FDG-PET and a CXCR4-PET for direct comparison. This is an imaging-only study. Therapy will not be affected by the study. The study is single-arm and not blinded.
People with inflammatory diseases are often treated with medications that act to suppress the immune-system, increasing the risk of catching infections. Consequently, vaccination with the pneumonia and seasonal flu vaccines is recommended for them. They were also prioritised to receive the COVID-19 vaccines early in the national rollout. However, the uptake of the pneumonia and seasonal flu vaccines among this group is lower than ideal. There may be many reasons why they do or do not seek to be vaccinated for these infections, such as the belief it may cause their disease to flare up or lack of knowledge of vaccines effectiveness. Anecdotally there was a high uptake of COVID-19 vaccines in adults with inflammatory conditions, however, concerns about vaccine-induced disease flare-ups and reports of complications deterred some from being vaccinated. A better understanding of why people do and do not seek vaccination may result in more targeted messaging for patients to help overcome vaccine hesitancy for these infectious diseases. This study aims to explore the drivers and barriers to being vaccinated among adults with common inflammatory conditions and on immune-suppressing medication. They will be invited to participate in a single, semi-structured interview. Interviews will be face-to-face, by telephone or video-call, last up to one hour, and digitally audio-recorded. They will explore participants' understanding of pneumonia, seasonal flu and COVID-19 and the risk they pose to their health, their understanding of vaccinations, beliefs of the benefits and risks of vaccinations for these infections, and reasons for seeking or not seeking vaccination. Findings will inform messaging about being vaccinated for these infections in patient education leaflets, such as those by patient charities regularly provided at speciality clinics. They will also be disseminated to healthcare professionals to help them better understand the drivers and barriers to vaccination.
